NAME    [Toc]    [Back]

     infocmp - compare or print	out terminfo descriptions

SYNOPSIS    [Toc]    [Back]

     infocmp [-d] [-c] [-n] [-I] [-L] [-C] [-r]	[-u] [-s d| i| l| c] [-v] [-V]
	   [-1]	[-w width] [-A directory] [-B directory] [termname . . .]

DESCRIPTION    [Toc]    [Back]

     infocmp can be used to compare a binary terminfo entry with other
     terminfo entries, rewrite a terminfo description to take advantage	of the
     use= terminfo field, or print out a terminfo description from the binary
     file (term) in a variety of formats.  In all cases, the boolean fields
     will be printed first, followed by	the numeric fields, followed by	the
     string fields.

   Default Options    [Toc]    [Back]
     If	no options are specified and zero or one termnames are specified, the
     -I	option will be assumed.	 If more than one termname is specified, the
     -d	option will be assumed.

   Comparison Options [-d] [-c]	[-n]
     infocmp compares the terminfo description of the first terminal termname
     with each of the descriptions given by the	entries	for the	other
     terminal's	termnames.  If a capability is defined for only	one of the
     terminals,	the value returned will	depend on the type of the capability:
     F for boolean variables, -1 for integer variables,	and NULL for string

     -d	     produces a	list of	each capability	that is	different between two
	     entries.  This option is useful to	show the difference between
	     two entries, created by different people, for the same or similar

     -c	     produces a	list of	each capability	that is	common between two
	     entries.  Capabilities that are not set are ignored.  This	option
	     can be used as a quick check to see if the	-u option is worth

     -n	     produces a	list of	each capability	that is	in neither entry.  If
	     no	termnames are given, the environment variable TERM will	be
	     used for both of the termnames.  This can be used as a quick
	     check to see if anything was left out of a	description.

   Source Listing Options [-I] [-L] [-C] [-r]
     The -I, -L, and -C	options	will produce a source listing for each
     terminal named.
     -I	     use the terminfo names
     -L	     use the long C variable name listed in <term.h>
     -C	     use the termcap names
     -r	     when using	-C, put	out all	capabilities in	termcap	form

     If	no termnames are given,	the environment	variable TERM will be used for
     the terminal name.

     The source	produced by the	-C option may be used directly as a termcap
     entry, but	not all	of the parameterized strings may be changed to the
     termcap format.  infocmp will attempt to convert most of the
     parameterized information,	but anything not converted will	be plainly
     marked in the output and commented	out.  These should be edited by	hand.

     All padding information for strings will be collected together and	placed
     at	the beginning of the string where termcap expects it.  Mandatory
     padding (padding information with a trailing '/') will become optional.

     All termcap variables no longer supported by terminfo, but	which are
     derivable from other terminfo variables, will be output.  Not all
     terminfo capabilities will	be translated; only those variables which were
     part of termcap will normally be output.  Specifying the -r option	will
     take off this restriction,	allowing all capabilities to be	output in
     termcap form.

     Note that because padding is collected to the beginning of	the
     capability, not all capabilities are output.  Mandatory padding is	not
     supported.	 Because termcap strings are not as flexible, it is not	always
     possible to convert a terminfo string capability into an equivalent
     termcap format.  A	subsequent conversion of the termcap file back into
     terminfo format will not necessarily reproduce the	original terminfo

     Some common terminfo parameter sequences, their termcap equivalents, and
     some terminal types which commonly	have such sequences, are:

	  terminfo		      termcap	Representative Terminals

	  %p1%c			      %.	adm
	  %p1%d			      %d	hp, ANSI standard, vt100
	  %p1%'x'%+%c		      %+x	concept
	  %i			      %i	ANSI standard, vt100
	  %p1%?%'x'%>%t%p1%'y'%+%;    %>xy	concept
	  %p2 is printed before	%p1   %r	hp

   Use=	Option [-u]
     -u	     produces a	terminfo source	description of the first terminal
	     termname which is relative	to the sum of the descriptions given
	     by	the entries for	the other terminals termnames.	It does	this
	     by	analyzing the differences between the first termname and the
	     other termnames and producing a description with use= fields for
	     the other terminals.  In this manner, it is possible to retrofit
	     generic terminfo entries into a terminal's	description.  Or, if
	     two similar terminals exist, but were coded at different times or
	     by	different people so that each description is a full
	     description, using	infocmp	will show what can be done to change
	     one description to	be relative to the other.

     A capability will get printed with	an at-sign (@) if it no	longer exists
     in	the first termname, but	one of the other termname entries contains a
     value for it.  A capability's value gets printed if the value in the
     first termname is not found in any	of the other termname entries, or if
     the first of the other termname entries
     that has this capability gives a different	value for the capability than
     that in the first termname.

     The order of the other termname entries is	significant.  Since the
     terminfo compiler tic does	a left-to-right	scan of	the capabilities,
     specifying	two use= entries that contain differing	entries	for the	same
     capabilities will produce different results
     depending on the order that the entries are given in.  infocmp will flag
     any such inconsistencies between the other	termname entries as they are

     Alternatively, specifying a capability after a use= entry that contains
     that capability will cause	the second specification to be ignored.	 Using
     infocmp to	recreate a description can be a	useful check to	make sure that
     everything	was specified correctly	in the original	source description.

     Another error that	does not cause incorrect compiled files, but will slow
     down the compilation time,	is specifying extra use= fields	that are
     superfluous.  infocmp will	flag any other termname	use= fields that were
     not needed.

   Other Options [-s d|i|l|c] [-v] [-V]	[-1] [-w width]
     -s	     sorts the fields within each type according to the	argument

	     d	  leave	fields in the order that they are stored in the
		  terminfo database.

	     i	  sort by terminfo name.

	     l	  sort by the long C variable name.

	     c	  sort by the termcap name.

	     If	the -s option is not given, the	fields printed out will	be
	     sorted alphabetically by the terminfo name	within each type,
	     except in the case	of the -C or the -L options, which cause the
	     sorting to	be done	by the termcap name or the long	C variable
	     name, respectively.

     -v	     prints out	tracing	information on standard	error as the program

     -V	     prints out	the version of the program in use on standard error
	     and exit.

     -1	     causes the	fields to be printed out one to	a line.	 Otherwise,
	     the fields	will be	printed	several	to a line to a maximum width
	     of	60 characters.

     -w	     changes the output	to width characters.

   Changing Databases [-A directory] [-B directory]
     The location of the compiled terminfo database is taken from the
     environment variable TERMINFO .  If the variable is not defined, or the
     terminal is not found in that location, the system	terminfo database,
     usually in	/usr/share/lib/terminfo, will be used.	The options -A and -B
     may be used to override this location.  The -A option will	set TERMINFO
     for the first termname and	the -B option will set TERMINFO	for the	other
     termnames.	 With this, it is possible to compare descriptions for a
     terminal with the same name located in two	different databases.  This is
     useful for	comparing descriptions for the same terminal created by
     different people.
